Input: evdev - Add ioctl to block suspend while event queue is not empty.

Add an ioctl, EVIOCSSUSPENDBLOCK, to enable a wakelock that will block
suspend while the event queue is not empty. This allows userspace code to
process input events while the device appears to be asleep.

The current code holds the wakelock for up 5 seconds for every input
device and client. This can prevent suspend if sensor with a high data
rate is active, even when that sensor is not capable of waking the
device once it is suspended.
